TYPnwnrrIN MACHINE.

Application filed October 10, 1925. Serial No. 61,662.

This invention relates to interponent or shield devices for typewriting machines, for preventing certain characters typed on a work-sheet from being carbon-copied on an underlying record-sheet, and is in the nature of an improvement on the device disclosed in the application of J. A. B. Smith, Serial No. 60,190, filed Gctober 3, 1925. They may be advantageously used for typewriting bank-checks and drafts arranged in sheet-form and for making a condensed record of them at the same time.

To save space on a check-register or reoord-sheet, it is desirable to have thereon but one line of record-data of a check, the payees name and the numerical amount of the check, and have that line spaced nearer the preceeding line of data on the recordsheet than it is on the overlying check-sheet. In said application, provision is made of means for accomplishing these results, which includes a paper-table mounted on a typewriter-carriage and having side flanges arranged for engagement in open slots, and a thin movable shield for guiding the same and limiting its upward movement'; said shield being arranged to be interposed, at will, between a check-sheet and an underlying record-sheet, to prevent certain characters typed on the former from being carbon-copied on the letter.

In the present invention, pro 'ision is made of a paper-table mounted on a typewriter-carriage and having side flanges provided 7 with narrow lengthwise slots through which may project lateral stoppieces of the movable shield for limiting both its upward and downward movement when interposed between a check-sheet and its record-sheet below the printing line, for preventing certain characters typed on the latter being carbon-copied on the recordsheet. Limiting the downward movement of the shield is especially advantageous, since its lower edge may be stopped in convenient position to be raised above the printing line by line-spacing the platen one ortwo times, the number of line-spacing erations needed being determined whether t e machine is set for single or double line spacing,

Other features and a vantages will here inafter appear.

Figure 2 is a fragmentary cross-section-. al view of the same.

Figure 3 is a fragmentary front view of th same, showing the work-sheetadvanced for printing a second line of characters thereon, the shield being lowered below the second line.

Figure 4 is a diagrammatic view of 'a sheet or web of bank-check forms.

A typewriter-platen 10, on a shaft 11, mounted in'the carriage side frames 12, may have line-spacing means including a fingerwheel 13 and a ratchet-wheel 14, the latter being operated by linger-piece mechanism, not shown. Two feed-rolls 17, engaging against the upper sideof the platen 10, are carried by fingers l8 fastened to arms 19, the latter being slidably and piv-otally mounted on a platen-carriage-rod 20. Feedrolls 21 and 22 are arranged to be thrown against or away from the lower side of the platen by means not shown. A papertable 23 may have an apron-extension24 under the platen. The above-described parts may be the same as on an Underwood type writing machine.

A paper-table or chute. 30, having two forwardly-extendng flanges 31. arranged for serving-as side gages for work-sheets, may be supported by two arms 32 fast on side framesliZ, so that the lower edge 33 of the table may be in close proximity to the platen, at a point, say degrees above the print ing line, the latter being indicated by a type 34. Back or body portions 35 of the papertable may be slightly inclined rearwardly. Each of the flanges 31 may have a narrow, lengthwise slot 36, in close proximity to the face of the paper-table 30. An interponent or shield 38 of substantially rectangular shape, made preferably of relatively hard, flexible cardboard, may have two laterallyprojecting stop-pieces 39, which may extend outward through the slots 36, and serve to limit the upward and downward. movements of the shield which is arranged on the -moving sheets.

face of the table 30, to fit loosely between the flanges 31 and be guided thereby. The stoppieces engaging in the slots also serve to prevent displacement of the shield from the table. The shield may extend downwardly from the lower edge 33 of the table to be substantially tangent to the platen 10 at the printing line thereof, with its lower edge l below the printing line (see Figure 3) when the lower sides of the projecting pieces 39 are down against the lower ends of the slots 36.

A plurality of bank-checks 50, 50", etc., may be fastened one below another along perforate lines 51, to form a checlesheet 52, having a width slightly less than the distance between the flanges 31. For conveniently typewriting characters on the checks and making a condensed record of them at the same time, the check-sheet 52 with a wider underlying record-sheet 53 and an inter-leaved carbon-sheet may be inserted around the platen from the rear in the usual way. The three sheets may be advanced together as far as the lower edge of the shield 88. There the check-sheet 2 and the carbon-sheet 5 f may be passed in front of the shield 38 and advanced to bring the first or leading check in position for typing the payees name and the numerical amount of the check. The record sheet will pass below and behind the shield, and under upper feed-rolls 17 positioned at either side of paper-table 30. In this position, friction between the work-sheets and the shield may hold the lower edge 40 of the shield 38 above the printing line, and permit characters typed on the check 50 to be carbon-copied on the record-sheet 53 (see Figures 1 and 2). The payees name and the numerical amount of the first check may be typed in one line as usual. The check, carbon and record sheets may now be line-- spaced together to bring the check 50 in position for writing the amount of it in words below the payees name. The. lower edge l0 of the shield 38 may be pushed down below the printing line (see Figure 3), and stopped at a certain predetermined point by arrangementof the stop-pieces 39 in the slots 36. After writing the amount of the check in words, which the shield prevents being carbon-copied, the carriage may be moved to the right by a carriage-fingerpiece, not shown, and the platen 10 linespaced thereby, as usual in an Underwood typewriter. The platen 10 may be further line-spaced in the usual way, if necessary, for raising above the printing line the shield 38, which, at the beginning of these linespacing operations, is held tightly between the carbon-sheet 54: and the record-sheet 53, and is moved upwardly by friction of the The feed-rolls 21 and 22 may now be thrown ofi, and the check-sheet pulled ahead, to bring the second check 50 to proper position for having its payees name and numerical amount typed, as was done on the first check 50 t can be readily seen that employmentof the herein-disclosed means permits lines of recorddata of checks to be conveniently spaced much nearer on a record-sheet than they appear on the overlying oheck-sheet. The record-sheet- 53 is held against movement by the feed-rolls while the second sheet is advanced. F or holding the typed portion of the check-sheet 52 against the face of the table 30, a fingerpiece 55, more fully described in the patent to Jesse A. B. Smith, No. l,t8l,67l, dated March 18, 1924, may be used. be severed from the sheet or web 52 when they have been typed, and advanced above the paper-table 30, or after the sheet has been removed from the machine, and the checks have been dated and signed.

Variations may be resorted to within tl e scope of the invention, and portions of the improvements may be used without others. l-Iaving thus described my invention, 1 (31311111 1.
